aluminum heat sink amazon: 6063-T5 aluminium, tolerance 0.20 mm, surface hard anodize Type III, 25-40 µm, lead time 20 working days, MOQ 5000 pcs. Capacity 800,000 pcs for LED high bay lighting. Drawing review and first-article report included.
aluminum heat sink amazon
Key Takeaway
aluminum heat sink amazon projects balance dimensional stability, unit cost, and delivery time. In production, we hold general tolerance at ±0.15 mm, with 0.3 mm fin thickness and 1.5 mm fin pitch, achieving 0.62 K/W thermal resistance. Type III hard anodize at 25-40 µm supports durability. Lead time is quoted at 10 working days when tooling design and process validation run in parallel, rather than relying on final inspection.
aluminum heat sink amazon sits at the intersection of three constraints that rarely agree: dimensional stability, unit cost, and delivery time. This page breaks down how we resolve them in production rather than in a brochure.

Market and Technical Context
Lead time pressure has compressed across LED high bay lighting. What used to be a 12-week tooling and qualification cycle is now quoted at 10 working days, which only works if tooling design and process validation run in parallel.
The technical bar keeps rising: assemblies that once accepted ±0.15 mm now specify tighter control on critical features, which pushes the decision to tooling design rather than to final inspection.

How We Manufacture It
Tooling is designed around the measured capability of the process, so ±0.15 mm is a consequence of tooling geometry rather than an inspection filter. That is why 10 working days is realistic instead of optimistic.
Heat treatment and surface treatment are scheduled as controlled steps, not afterthoughts. hard anodize Type III, 25-40 µm is applied to a defined thickness range and verified, because variation here causes more field failures than dimensional drift.
Deburring and edge conditioning are specified on the drawing for aluminum heat sink amazon. A sharp edge that passes dimensional inspection can still fail assembly, so edge break is a controlled parameter rather than a cosmetic one.

Material and Surface Finish
Surface specification for aluminum heat sink amazon is hard anodize Type III, 25-40 µm, chosen for the service environment in LED high bay lighting. Thickness is verified on a reference coupon from the same batch rather than assumed from process settings.
Substitution requests are common when pure copper C110 goes on allocation. We qualify any substitute against the same ±0.15 mm and hard anodize Type III, 25-40 µm criteria before shipping, and provide the certificate with the change.
Recycled content and RoHS/REACH declarations are available for aluminum heat sink amazon on request. If your LED high bay lighting customer audits material origin, ask for the mill certificate at quote stage, not at delivery.

Tolerance and Inspection
General dimensions on aluminum heat sink amazon are held to ±0.15 mm; critical features are identified on the drawing and controlled separately with a tighter band.

First-article inspection for aluminum heat sink amazon reports every dimension on the drawing, not a sample of them. That report is the reference for the rest of the batch and for any future reorder.
Process capability is tracked per feature. Where Cpk falls below the agreed threshold on aluminum heat sink amazon, we either adjust the process or reclassify the feature, rather than sorting parts at the end.

Where It Is Used
Maintenance access matters. Where aluminum heat sink amazon is a wear item, we recommend specifying it as a spare with its own part number so reorder does not require a full drawing review.
Retrofit requests are common: an existing assembly needs aluminum heat sink amazon in a slightly different size. Because the process window is already known, 10 working days on a retrofit is usually shorter than on a new part.
What to Confirm Before Ordering
Ask for the first-article report before you ask for a price cut on aluminum heat sink amazon. A supplier who cannot produce dimensional data at 500 pcs will not produce it at 120,000 pcs.
Define critical features at quote stage. Moving a feature from general ±0.15 mm to critical after tooling adds cost and extends 10 working days, which is the most avoidable delay in custom sourcing.
FAQ: Your Questions Before Ordering
What tolerance can you hold on aluminum heat sink amazon?
Prototype quantities start well below production minimums. Production runs for aluminum heat sink amazon start at 500 pcs, which is where the process window is proven and unit cost stabilises.
How long does production take for aluminum heat sink amazon?
Standard lead time for aluminum heat sink amazon is 10 working days after drawing approval and tooling sign-off. Prototypes are typically faster because they bypass tooling, and repeat orders are faster still because tooling exists.

Can you work from our existing drawing?
Yes. Send the drawing in any common format. We review it for manufacturability first and flag any feature where ±0.15 mm would require an extra operation, so you can decide before tooling.

Do you provide material and inspection certificates?
Yes. Material certificates, heat-lot traceability, and first-article inspection reports ship with the order. If your LED high bay lighting customer requires additional documentation, specify it at quote stage.
Can you prototype before tooling?
Changes are documented against the original first-article report. We identify which dimensions are affected, requote only the affected operations, and tell you whether existing stock of aluminum heat sink amazon remains usable.

Frequently Asked Questions
What is the lead time for aluminum heat sink amazon orders?
Lead time is quoted at 10 working days when tooling design and process validation run in parallel. This is realistic because ±0.15 mm tolerance is built into tooling geometry rather than added by final inspection. Longer cycles may apply if heat treatment or Type III hard anodize at 25-40 µm requires separate scheduling.
What material is used for the heat sink?
The article specifies pure copper C110 for the heat sink. Copper C110 provides high thermal conductivity, supporting a thermal resistance of 0.62 K/W. If your application requires aluminum instead, confirm material selection before ordering because thermal performance and weight will change.
What is the fin thickness and fin pitch?
Fin thickness is 0.3 mm and fin pitch is 1.5 mm. These values support compact fin arrays and a thermal resistance of 0.62 K/W. Thin fins at 0.3 mm require careful tooling design to maintain ±0.15 mm general tolerance during production.

What surface finish is available?
The specified surface finish is hard anodize Type III at 25-40 µm. This finish supports durability and corrosion resistance. Confirm whether your assembly requires masking or tighter control on critical features, because surface treatment is scheduled as a controlled process step.
What tolerance can you hold on critical features?
General tolerance is ±0.15 mm. For critical features, tighter control is achieved through tooling design rather than final inspection. The article notes that assemblies once accepting ±0.15 mm now specify tighter control, so confirm critical dimensions before ordering.
How do you achieve 10 working days lead time?
Tooling design and process validation run in parallel. Tooling is designed around measured process capability, so ±0.15 mm is a consequence of tooling geometry. Heat treatment and surface treatment are scheduled as controlled steps. This makes 10 working days realistic instead of optimistic.

What should I confirm before ordering?
Confirm material, fin thickness 0.3 mm, fin pitch 1.5 mm, thermal resistance 0.62 K/W, surface finish hard anodize Type III at 25-40 µm, general tolerance ±0.15 mm, and 10 working days lead time. Also confirm critical features needing tighter control and any heat treatment or surface treatment scheduling requirements.
